Engineering Selection Recommendations

Direct Equivalent (Preferred for Immediate Replacement):

68021-472HLF is the direct equivalent of 68021-472. Both are Amphenol ICC BERGSTIK® II series connectors with identical electrical and mechanical specifications. The primary distinction is product status: 68021-472HLF is active with RoHS compliance and bulk packaging, whereas 68021-472 is obsolete and RoHS non-compliant. For new designs or production requiring RoHS compliance, 68021-472HLF is the recommended selection.

Active Alternatives (72-Position, 2.54mm Pitch):

802-V3-072-20-001101 (Preci-Dip 802 series) and M20-9743646 (Harwin M20 series) are functionally equivalent alternatives with all critical parameters matching the original specification. Both are active products with modern compliance certifications (ROHS3). The 802-V3-072-20-001101 offers higher voltage rating (150VDC) and extended upper temperature capability (125°C). The M20-9743646 features cuttable connector design and is available in bulk packaging. Both maintain the required 3A per contact current rating and UL94 V-0 flammability rating.

Position Count Deviation (Not Recommended Without Design Review):

4-103330-0 (TE Connectivity AMPMODU Mod II) differs in position count (80 positions versus 72) and is therefore not a direct substitute. This part is suitable only if the application can accommodate the additional 8 positions and if mechanical board layout permits the increased connector footprint.

Compliance Considerations:

For applications requiring RoHS compliance, select 68021-472HLF, 802-V3-072-20-001101, or M20-9743646. The original 68021-472 and 4-103330-0 are RoHS non-compliant and should be phased out in new production.

Frequently Asked Questions (FAQ)

Q: Can 68021-472HLF directly replace 68021-472 without PCB modification?

A: Yes. Both connectors share identical pitch (2.54mm), position count (72), row spacing (2.54mm), mounting type (through-hole right-angle), and electrical ratings (3A per contact, 110V). No PCB layout changes are required.

Q: What is the primary difference between 68021-472 and 68021-472HLF?

A: The 68021-472HLF is the active production variant with RoHS compliance and bulk packaging. The original 68021-472 is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are Preci-Dip 802-V3-072-20-001101 and Harwin M20-9743646 compatible with the original 68021-472 footprint?

A: Yes. Both maintain the same pitch (2.54mm), position count (72), row spacing (2.54mm), and through-hole right-angle mounting. PCB footprints are compatible. Minor differences in contact dimensions and materials do not affect mechanical or electrical compatibility within the specified operating parameters.

Q: Why does 4-103330-0 have 80 positions instead of 72?

A: The TE Connectivity 4-103330-0 is a different connector variant designed for applications requiring higher position density. It is not a direct substitute for the 72-position 68021-472 and requires design review and PCB modification.

Q: Which substitute part offers the best compliance for new designs?

A: Both 802-V3-072-20-001101 and M20-9743646 are ROHS3 compliant active products. The 802-V3-072-20-001101 additionally offers higher voltage rating (150VDC) and extended temperature range (-55°C to 125°C). Selection depends on specific application requirements.

Q: Are there temperature range limitations when substituting with M20-9743646?

A: The M20-9743646 operates from -40°C to 105°C, which is narrower than the original 68021-472 range (-65°C to 125°C). Applications requiring operation below -40°C or above 105°C should use 68021-472HLF, 802-V3-072-20-001101, or 4-103330-0 instead.

Q: What is the difference between tin and tin-lead contact finishes?

A: Tin finish (68021-472, 68021-472HLF, M20-9743646) and tin-lead finish (4-103330-0) both provide corrosion protection and solderability. Tin-lead is an older standard; tin is preferred in modern RoHS-compliant designs. Both are electrically and mechanically compatible for this connector category.

Q: Can I use 802-V3-072-20-001101 in applications requiring 110V operation?

A: Yes. The 802-V3-072-20-001101 is rated for 150VDC, which exceeds the 110V requirement of the original specification. This part is suitable for 110V applications.
